RTX 4090 Gets Just 16 FPS in Cyberpunk 2077 RT Overdrive Preview
Upscaling or DLSS 3 Frame Generation are practically mandatory
Nvidia published a new YouTube video this morning showing Cyberpunk 2077's new RT Overdrive mode in action with a GeForce RTX 4090, along with a breakdown of the changes. The graphics are incredible, but so is the performance hit on the RTX 4090. The fully path-traced renderer brought the RTX 4090 to a snail's pace and ran the game at just 16 FPS natively with the mode active. To achieve favorable frame rates, DLSS 3's frame generation and upscaling were required. But let's take a moment to step back and dissect precisely what we're talking about here.
RT Overdrive mode is a brand-new rendering mode being added to Cyberpunk 2077 on April 11th. The new graphics mode replaces the game's current ray-tracing pipeline with a fully unified path-tracing solution that significantly expands the game's rendering engine. There's no hybrid rendering, only ray traced pixels. Nvidia has previously demonstrated this mode, and it notes that on average it needs 635 ray calculations per pixel — compared to just 39 rays per pixel with Battlefield V, one of the original launch games for RTX ray tracing.
The regular ray tracing modes in Cyberpunk 2077 were a hybrid rendering solution, consisting of rasterization in combination with ray-traced reflections, global illumination, and other effects. With the fully path-traced solution, every single light source in the game is simulated to generate the most realistic lighting, shadows, and reflections possible.
All light sources in the game are path-traced, in conjunction with Nvidia technologies including NVIDIA Real-Time Denoisers (NRD), NVIDIA RTX Direct Illumination (RTXDI), and Shader Execution Reordering (SER) to improve image quality and accelerate performance. It's basically the same overhaul that Nvidia did with Portal RTX, only now applied to a significantly more modern and demanding game engine.
Overdrive is the new Crysis
Nvidia's YouTube video demonstrates the absurd performance penalty of running a AAA title like Cyberpunk 2077 with full-blown path tracing enabled. Nvidia used a GeForce RTX 4090 to run the Overdrive tech demo at 4K resolution, and the GPU couldn't even hit 30FPS at native resolution.
To achieve playable frame rates, Nvidia used DLSS 3 frame generation in combination with image upscaling (DLSS 2 Performance mode) to get frame rates back into the triple digits. This is similar to Portal RTX — another fully path-traced game, where the RTX 4090 also needed DLSS 3 frame generation and/or upscaling to achieve playable frame rates.
This should put into perspective how much more demanding 3D light simulation is compared to just faking it. But thankfully, we're now at the point where good quality light simulation can be done in real-time, even if it still generally needs upscaling to get to decent frame rates.
We don't know the system requirements yet for this new Overdrive mode, but its safe to say you'll probably need a top-tier RTX 30-series GPU, or one of Nvidia's RTX 40-series GPUs, to run Overdrive mode at high frame rates. Considering Nvidia was running at 4K, you can probably get decent performance at 1080p with far less potent GPUs than the RTX 4090, and Cyberpunk 2077 does support both DLSS 2 and AMD FSR 2.1 upscaling.
We'll have to see what performance looks like on other GPUs when the free update arrives on April 11.

elforeign Any ideas on a 12GB 3080 at 1440P or 1080p with DLSS2?Reply
If it can run at 30-40 fps that would be just fine. -

So, 4090 is getting maybe 16~24 fps at 4K native. Dropping to 1080p native would probably get 3-4 times that performance, and then Frame Generation give you another ~50% is what I'd guess (it could be more). If a 4090 can get 60~70 fps at 1080p native without FG, that would probably put a 3080 12GB at roughly half that level of performance. Turn on DLSS upscaling and I'd guess 1080p will be very playable, and 1440p should still break 30 fps.elforeign said:Any ideas on a 12GB 3080 at 1440P or 1080p with DLSS2?

Unolocogringo Give it a few more generations.Reply
Each generation gets more RT/ tensor/cuda cores. -
mhmarefat Glad to see billionaire companies are hard at work to shove "true ways of gaming" down our throats. Makes me wonder what was nvidia doing with introduction of RT with 20 series GPUs when years later even 4090 is biting dust here? Why enter this incomplete technology into gaming industry? The rich are hard at work to make themselves even richer.Reply
Don't let these greedy corporations dictate how you should enjoy your games people, just don't. They are shaping the future of PC Gaming for the worse (rich man's hobby). -
Third-Eye I wonder if overdrive RT requires an nvidia card to run because of ties to nvidia or if will it be available on AMD. :unsure:Reply
Current ray tracing in Cyberpunk 2077 is actually playable on a 6800 XT with about 50-60fps at 1440p using RT ultra and FSR 2 on performance and doesn't look too bad to be honest. There is some grainly blocky steam and smoke effects and some other artifacts like ghosting on physics objects, but everything else looks pretty decent all things considered. -

My understanding is that it's still just using DXR API, though I could be wrong. I know SER is an Nvidia tech, but I don't know that it strictly requires an Nvidia card. I think it's something that happens if the tech is available on a GPU — because only 40-series supports SER. So FG, SER, and OMM are new things that need Ada Lovelace and I assume will simply not be used / supported if you're not on RTX 40-series or later.Third-Eye said:I wonder if overdrive RT requires an nvidia card to run because of ties to nvidia or if will it be available on AMD. :unsure:

PlaneInTheSky Those RTX ON/OFF screenshots make me realize how little I care about raytracing. The difference is minuscule and irrelevant. Certainly not worth cutting your FPS in half.Reply -
Alvar "Miles" Udell The irony of having to use AI generated frames and/or lower image quality in order to enable a setting which raises image quality.Reply
